Topic: can someone help me with caocl2? (Read 400 times)

An electroplating wastewater with an average flow of 4 L s-1 contains 258 mg L-1 NaCN. Determine the amounts of chlorine as Ca(OCl)2 and NaOH required to (a) oxidize the cyanide to cyanate; (b) oxidize the cyanide to CO2 and H2O. should ı solve it according to cl2?

No, you have to calculate how much Ca(OCl)2 should be used. While the process is equivalent to reaction with just chlorine, you don't use chlorine, but Ca(OCl)2. That's what "chlorine as Ca(OCl)2" means.
